On rhenium(I)–silver(I) cyanide porous macrocyclic clusters

Author affiliations


The first cyanide rhenium(I)–silver(I) clusters were synthesized in the course of simple one-pot high-yielding reactions. This new class of obtained self-assembled, cyclic octanuclear complexes is composed of pseudo-square-shaped {Re4Ag4(μ-CN)8} units, which, along with PPh3 ligands, adopt an approximately block-like overall geometry. We discovered that the studied cavity-shaped clusters feature a channeling crystal network capable of hosting smaller molecules and exhibit the ability to undergo reversible guest solvent sorption. Depending on the reaction conditions, the tetranuclear complex [Re2Ag2(μ-CN)4(CO)4(PPh3)6] and the species of the formal motif {ReAg1.5(CN)2.5(CO)2(PPh3)2} can be formed.
